Abstract

Graft copolymers of poly(Nโ€isopropylacrylamide) (PNIPAAm) on a poly(acrylic acid) backbone retain the temperatureโ€induced phase transition behavior of PNIPAAm over a wide range of compositions even at pH 7,4 and should be useful for sustainedโ€release, bioadhesive drug delivery systems at physiologic conditions.

A series of temperature-responsive hydrogels were prepared by grafting oligo(N-isopropylacrylamide) (ONIPAAm) chains onto a crosslinked poly(acrylic acid) (PAAc) network, intending an application to drug delivery systems (DDS). Cloud points and swelling ratios of the obtained PAAc-graft-ONIPAAm gels
